Where 238 fits
Why 238 is special
Cape Verde is an Atlantic archipelago that was uninhabited before Portuguese settlement, and its creole culture formed entirely from that encounter.
Same number, different meanings
How 238 is understood across different contexts — never implying one meaning because of another.
- Mathematics
Cape Verde is an Atlantic archipelago that was uninhabited before Portuguese settlement, and its creole culture formed entirely from that encounter.
- Science
Uranium-238 constitutes over 99 percent of natural uranium and is not readily fissile. It absorbs neutrons to become plutonium-239, which is how breeder reactors produce fuel.
- Geography
+238 reaches Cape Verde, which had no population before the fifteenth century. Its language and music developed from the meeting of Portuguese and West African peoples on previously empty islands.

In historical numeral systems
Egyptian
2 coils of rope, 3 hobbles, 8 strokes
2 × 100 + 3 × 10 + 8 × 1 = 238. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 vertical wedges (sixties place), 5 corner wedges + 8 vertical wedges (units place)
3 × 60 + 58 = 238. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sigma, then lambda, then eta, marked as a numeral
sigma-lambda-eta + keraia
sigma + lambda + eta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
resh, then lamed, then het
resh-lamed-het
resh (200) + lamed (30) + het (8) = 238, written in descending order.
Maya
2 bars + 1 dot (upper, twenties place) over 3 bars + 3 dots (lower, units place)
11 × 20 + 18 = 238. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
